To evaluate the outcomes, the patients', and their partners' satisfaction concerning the AMS Spectra penile prosthesis implantation.


Twenty-two unresponsive or dissatisfied patients with phosphodiesterase 5 inhibitor oral therapy or prostaglandin intracavernous injection underwent a Spectra penile prosthesis implantation. No major intraoperative or postoperative complications were observed. The preoperative erectile dysfunction (ED) was rated by the International Index of Erectile Function (IIEF) questionnaire. The patients and their partners were submitted to the IIEF and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaires through telephonic interviews at the third, sixth, and 12th months after the penile surgery.


This study demonstrates that 86.4% of the patients and 52.6% of their partners are satisfied by the AMS Spectra penile prosthesis. The preoperative average IIEF score was equal to 28.5 (range 13-39). The postoperative IIEF rates were 47.7 (43-53), 51.8 (48-58), and 53.9 (50-58) at the third, sixth, and 12th months, respectively. The patient average EDITS score amounted to 39.5 (31-48), 43.4 (36-50), and 45.2 (38-50) at the third, sixth, and 12th months, respectively. The increase between the preoperative and postoperative IIEF parameters resulted to be statistically significant (P <.05) as well as the increase in EDITS at the third, sixth, and 12th months postoperatively.


The AMS Spectra is a reliable device to treat ED as shown by the high grade of the patients' satisfaction. Moreover, the AMS Spectra is highly convenient in terms of cost savings in comparison to an inflatable device. In selected patients, this prosthesis should be considered as an effective solution to treat severe ED.
